CONNECTION ROD FOE. OIL-WELL WALKING BEAMS.

Application filed July 8,

To all whom it may concern:

Be it known that I, IVILLIAM F. RESOHKE, a citizen of the United States, residing at Vichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Connection Rods for Oilell alking Beams, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this application.

The object of my inventlon is to eliminate the usual crank, which is placed on the shaft.

A further object of my invention is that when the crank is eliminated, and by the use of a pinion as substitute for said crank greater power may be had for the reciprocating movement of the walking beam.

Referring to the drawings, Fig. 1 is a side view of the mechanism and fragment of walking beam. Fig. 2 is an enlarged sectional detail on line A in Fig. 1, looking in the direction of the arrow. Fig. 3 is a side view of the adjustable guide plate.

Fig. 4 is an edge view of said plate, parts removed for convenience of illustration.

1 is a drive shaft, which is firmly attached by means of key 2, to a sleeve 3, said sleeve being recessed into a pinion 4L, and fastened firmly thereto by means of bolts 5, said pinion being interposed between guide plates 6 and an internal tooth loop rack 7 of a yoke, said loop rack having guide plates 8, functioning as guides to hold the rack in alinement with said pinion. 9 is a walking beam, said yoke being attached to a connecting bar 11. 12 designates reinforcing rods, functioning as bracing means for the said rack gear 7, the said rods being threaded to the loop rack at 13, and extending upward and passing through a plate 14:, and tensioned by nuts 15. The said guide 6 is made in two members slidably connected, and when adjusted, held firmly by means of bolts 16, said plates, having bosses 17 and 17, said bosses being spacing means to firmly connect to supporting bands 18, said bands being means for supporting in proper position the guide member 6. 19 is an adjusting rod with one end screwed into boss 17, and the oppo site end passing through an ear 20, and having lock nuts 21, for holding said rod firmly when properly adjusted, 22 is a block having rollers 23 trunnioned around the 1923. Serial No. 649,260.

edges thereof, functioning as a nonfriction means between said block, and said guide 6 during the reciprocation of said rack 7 bythe rotation of pinion 4. 24: is a plate functioning as a guide, extending over plate 6, and also functioning as means to hold block 22 in proper engagement, on the edge of said guide plate 6, said block and guide plate being means for holding the teeth in loop rack, and those of the pinion in mesh. It will be understood that when the pinion is carrying the block 22 around the curved end, to its reversed motion, which occurs by engagement on the opposite side, the block will rotate on its axis, which is a bolt 25,

having a shoulder .26 to bind firmly against I the face of pinion 4, so that it will not bind said block 22, and plate 24 and all of said members 22, 2a, 25, being concentric to said pinion 4, it will also be observed and understood, that the length of the stroke may be varied by increasing or decreasing the length of the straight parallel planes of the rack, and the guide interposed within said rack. I therefore would not be confined to make the elongation of the rack to any certain length, as the stroke of the rocker arm, in pumping or drilling may vary according to requirements. Therefore my illustration as in Fig. 1 is simply illustrating the principle of my invention.

It will also be understood that pinion 4 shown, is mounted on a drive shaft, being rotated by some approved type of motive power.

The drawings herein shown and referred to are made to a specific shape and propor tion diagrammatically. I therefore do not confine myself to such as the mechanism may be modified in proportions to accommodate and function for the purpose to which the principle may be applied.

I am aware that similar devices such as elongated internal rack gears, operated by pinions have been made and applied to various purposes, I therefore do not claim such broadly, but what I do claim, and desire to secure by Letters Patent is:

1. A walking beam connecting rod including a rack loop, a pinion rotating by motive power and arranged within the loop, a guiding plate mounted within the loop with substantial parallelism with therack teeth of the same and maintaining the pinion in mesh with the teeth of the said loop rack, an elongated plate carried by the pinion and provided in its edge with rollers arranged to engage the edge of the said guiding plate, said elongated plate having pivotal movement on an axis coinciding With that of the pinion, transverse supporting bars extending across and bracing the loop rack and supporting the said guiding plate, an adjusting rod connected to said guiding plate for maintaining the same in proper position with relation to the loop rack, a bar for connecting the loop rack to a walking beam and brace rods located at opposite sides of the bar and connecting the outer end of the same with the sides of the loop rack.

2. A walking beam connecting rod including a yoke, a bar extending from the yoke and adapted to be connected to a walking beam, said yoke being provided with a loop rack, brace rods located at opposite sides of the bar and connesting the outer ends of the same with the sides of the yoke, a center guiding plate arranged within the yoke, transverse bars extending across the yoke and secured to the same and to the guiding plate for supporting the latter, said guiding plate being com posed o't overlapped stations adjustable on each other, a pinion arranged within the yoke and interposed between the loop rack to the guiding plate and held in mesh with the loop rack by the said guiding plate, a block pivotally mounted on a pinion and provided with rollers arranged to ride on the guiding plate at the edge thereof, a plate engz'iging over the .tace of the block and the guiding plate, a screw constituting the pivot ot the said block and pinion, said pinion having a depression, and a sleeve securely mounted on the pinion in the said depression and having means for fixing it to a drive shaft.
